Bounds for the numner of matchings in regular graphs

Date: 
Tuesday 22nd January 2008 - 12:00 to 12:30
Venue: 
INI Seminar Room 1
Abstract: 

In this talk I will first present a group of conjectures on the number of k-edge matchings in a regular graph on n vertices. Next I will present the partial results obtained so far. In order to get lower bounds for the number of matchings for all densities k/n we make use of the fact that the matching polynomial of a graph has real zeros.
